2 Claims. (CI.129 16.7-)'

This invention relates to improvements in visible card indexes and particularly to improvements in means for holding a card on the rear side of a card holder.

The invention provides an index card for the rear side of the card holder of a conventional form of visible index for support on the rear side of the card holder without notching the. margin of the card to receive the center stitch that holds the transparent tip on the card holder. The invention obtains this result, by employing a notched insert inserted into the transparent tip ofa conventional card holder on the rear side to provide a marginal portion extending beyond the tip-to provide a rear card retaining flange for receiving a margin of the rear index card to detachably retain it on the card holder. The insert is notched in ,thecentral portion to receive the center stitch at the rear side of a card holder that secures the transparent tip to the supporting sheet. The free ends of the card retaining insert are also provided with projections for cooperation with the means that secures the ends of the tip to the supporting sheet of the card holder in order that the insert is held in interlocked relation on the card holder against accidentaldetachment.

In the drawings:

Fig. 1 shows a conventional card holder having the hinged portion rotated on its hinge into an upwardly extending position relative to the supporting lug to illustrate the rear side of the card holder with the notched insert and record card applied to the rear side of the card holder.

Fig. 2 is an enlarged cross section taken on line 22 of Fig.1.

Fig. 31s an enlarged cross section taken on lines 3-3 of Fig. 1.

- Fig. 4 is an enlarged cross' section taken on line 4-4 of Fi 1. Y

Fig. 5 shows the notched insert formed with the rear card retaining flange in perspective.

The invention is applied to a conventionalform of card holder having a supporting sheet I provided with a row of openings 2 arranged in a line spaced inwardly from one edge of sheet I. These openings 2 separate a marginal portion along one edge of sheet I for attachment to lug 3 having the ends extending beyond the side edges of sheet I, as shown in Fi 1. The ends of the lugs may be engaged in the channels on a supporting structure for the cardholder. A plurality of card holders are mounted in overlapping offset relation through the cooperation of lugs 3 thereon in a manner well knownin the art to support indexcards on the front faces of sheet I withtheir free margins in visible indexed relation. The major portion of supporting sheet I is hingeable relative to the marginal portion secured to lug 3 so that this major portion of supporting sheet I may be moved into the position shown in Fig. 1 to expose a card supported on the rear face. Supporting sheet I is formed with diagonal slots 4 adjacent hinge openings 2 for receiving the corners of record cards in intere'ngaged relation on both sides of supporting sheet I in order to retain one marginattached to the card holder.

The free margin of supporting sheet I is embraced by a foldedstrip of transparent plastic material forming a tip 5 having a front fold portion 6 provided with an inturned lip I on the free edge thereof, as shown in Figs. 2 and 3. The rear fold '8 engages the rear face of supporting sheet I, in the manner shown in Figs. 1 to 4 so that it lies substantially flat against the rear face of sheet I. Wire stitches 9 are inserted through both the front and rear folds 6 and 8 respectively, of tip 5 and supporting sheet I to rigidly secure the tip in' position on the free margin of supporting sheet I. The corners of supporting sheet I are usually cut out to receive the end of wire stitch 9 extending through the front and rear folds 6 and 8 of tip 5 while the other end of stitch 9 engages only supporting sheet I providing for compensation for differences between the coefficients of expansion of sheet I and tip 5, in a manner well known in the art. The central portion of rear fold 8 of tip 5 has the central portion of the margin thereof secured to supporting sheet I by a wire staple Ill, in the manner shown in Figs. 1 and 2. One end of the staple extends through fold 8 and sheet I while the opposite end extends beyond the edge of fold 8 where it extends through sheet I only.

A rectangular imperforate record card II may have one margin engaged under front fold portion 6 of tip 5 and the corners of the opposite margin extended through slots 4 in supporting sheet I for supporting card I I on the front face of supporting sheet I so that the margin covered bythe fold portion 6 of tip 5 will normally lie in visible index relation where a series of record cards are supported by a series of card holders arranged in overlapping offset relation to provide a visible index. I

Record cards have also been placed on therear face of these conventional card holders. They require the notching of the central marginal por tion at the position where wire stitch III is located in order that the remaining marginal portion of a rear card may be inserted between rear fold 8 of tip 5 and the marginal portion of supporting sheet I. Due to the rear fold portion 8 lying substantially fiat against the rear face of supporting sheet I it is difiicult to insert a card margin under fold portion 8, particularly in view of the free edge portion fold 8 being closely secured to supporting sheet I by staple III.

The present invention is designed to eliminate the difficulty experienced with the present com- 3 mercial visible card indexes in placing a card on the rear face of the card holder.

The improved construction includes the proof the rear fold portion 8.

tip 5 Will extend to the folded portion of the tip in substantially coincident relation, With the'free margin of supporting sheet I, as shown in'the drawing. The central portion of insert it is notched at It to receive central staple or wire stitch While the opposite margin of insert I is formed with an inturned lip I! to provide a rounded edge that will facilitate the insertion of a recordcard margin under inturned lip I i. This last mentioned edge of insert [5 extends inwardly toward the centralportion of supporting sheet i beyond the inner edge of rear fold portion 8-01" tip 5 a sufficient distance to provide the rear card retaining flange It.

Theends of insert it are provided with projections '19 that are adapted to extend between staples S-andthe outer foldportion of tip-5, in the manner shown in Fig. l, to interlock'insert [5 with the card holder to normally prevent its removal from tip 5. By flexing insert it to shorten the distance between the ends suificiently, projections l9 may be easily inserted under wire stitches 9 in applying the insert into the position shown in Fig. 1 on the card holder. This insert is normally allowed to remain attached. to the card holder to provide rear card retaining flange i8 thereon.

Then, a, rear record card Ell is provided for the card holder having a rectangular iinperforate form so that a conventional rectangular record card can be used and applied on the rear side of the card holder without having to notch the outer margin to receive central wire stitch I 9; Record card 29 has one margin engaged under rear card retaining flange it of insert !5. The edge of card it does not extend into tip 55 but only under flange l8 to a position approaching the edge of rear fold 8, as shownin Figs 2 and 3. Then, the opposite margin of rear record card 20' may have the corner portions engaged in slots 4 near hinge openings 2, as shownin Fig. 1 to detachably mount card ill on the rear face of the card holder.

With this construction of insert to provide rear card holding flange [8, record card '20 can be very quickly and efilciently applied in position for support on the rear side of the card holder by first inserting one margin under flange iii-and then engaging the opposite corners in'diagonal slots 4. The rounded edge on flange is provided by inturned lipl'l facilitates the insertion of the margin of record-card 29 under flange IE2.

This improved construction for mounting a record card on the rear side ofa-conventional card-holder considerably reduces the cost of providing visible indexes with rear record cards both from the standpoint of the original installation of the inserts-andcards in the card holder and also effects a substantial saving in-labor in .operation by reducing the amount of time required in removing and replacing cards for-making entries and checking purposes according to. the usual operation of visible index record installations.
